UNITED ATES HARRY E. LIEDSTRAND, OF OAKLAND, CALIFORNIA.

WATER- HEATER.

Application filed April 18, 1922. Serial No. 555,091.

To all 'whom 'it may concern:

Be it known that I, HARRY E. LIEDSTRAND, a citizen of the United States,residing at Oakland, in the county of Alameda and State of California,have invented certain new and `useful Improvements in l/ater Heaters, ofwhich the following is a speciiication.

My invention is a hot water heater constructed and arranged to bemounted on a gas stove for heating water for a domestic boiler.

Referring to the annexed drawing in which my invention is illustratedand which forms a part of this specification:

Figure 1 is a front view of my wateil heater mounted on a gas stove andconnected to a domestic boiler.

Figure 2 is a plan view of my heater.

Figure 3 is a vertical longitudinal section of my water heater taken online 3 3 of Figure 2.

Figure 4 is a fragmentary vertical sectional View of the heating chambertaken on line 4 4 of Figure 3.

My heater includes a burner plate 1 and a water heating chamber 2 formedon the under side of said plate, said plate and said chamber both .beingrectangular in shape. except that the inner side of said chamber iscurved at the ends of the chamber. The plate 1 is supported on legs 3 bymeans of which my heater is mounted on the top of a gas stove 4. Theplate 1 is provided with two openings 5 and 6 near its ends respectivelyand within the ends respectively of the water chamber 2, which openingsrest over the burners 7 and 8 respectively of the gas stove. The chamber2 is formed with a hollow extension 9 extending inwardly from its leftend longitudinally of the plate 1 into the opening 5, and with a pair ofoppositely disposed hollow extensions 10 and 11 which extendtransversely into said opening, said extensions curving downwardly attheir extremities. An extension 12 is formed on the plate 1 whichextends longitudinally of the plate into the opening 5 opposite theextension 9, said extension 12 curving downwardly at its extremity. Thechamber 2 is formed with a hollow extension 13, extending inwardly fromthe right end of the plate 1 into the opening 6, and with a pair ofoppositely disposed hollow extensions 14 and 15 which extendtransversely into said opening, said extensions and 16 respectively,said walls dependingfrom the plate 1 or upper wall of the cham ber 2over half the depth of the chamber and extending from the outer wall ofsaid chamber into the rear portion of said tongues, said deflectorscausing the water to circulate partly under themv and partly throughsaid extensions which are the hottest part of the chamber, being withinthe flameof the burner. An inlet 17EL and an outlet 18 are' provided inthe left end of the chamber 2 at the left end Jcorners of said chamber,to which are respectively connected inlet pipe 19 and outlet pipe 20 ofa domestic boiler 21. An inlet 22 and an outlet 23 may also be providedin the left end corners of the chamber for connection with the boilerwhen at the right of the chamber, said inlet and outlet being closed byplugs 24 when not in use.

The water circulating from the inlet 17 through the chamber 2 around theburners 7 and 8 and through the extensions 9, 10, 11, 14, 15 and 16 andout through the outlet 18 is effectively heated for the boiler 21.

Having described my invention, I claim:

A water heater adapted to be mounted on the burners of a gas stovecomprising a rectangularly shaped hollow member, said member beingprovided with openings for said burners, hollow extensionsl on saidmember projecting into said opening and having their ends curveddownwardly into said openings, deiiector plates mounted in verticalpositions in said member, some of said deflector plates being located insaid extensions through the center thereof and adapted to cause adequatecirculation of water within said member, means for connecting saidmember at one corner to a water discharge pipe and means for connectingsaid member at another corner to a water intake pipe.

In testimony whereof I aiiix my signature.
